Kevin claims he can draw a trapezoid with 3 right angles.Is this possible?explain

1 answer:

7 0

This is not possible. Since trapezoids are quadrilaterals, the sum of their angles must add up to 360. If three of the angles are right angles (90 degrees each), then the only possible measurement of the last angle would be 90 degrees, making a fourth right angle. With four right angles, this shape would be a square, not a trapezoid.

Find r(t) if r'(t) = 5t4i + 6t5j + t k and r(1) = i + j.

Vladimir [108]

$\mathbf r(t)=\displaystyle\int(5t^4\,\mathbf i+6t^5\,\mathbf j+t\,\mathbf k)\,\mathrm dt$
$\mathbf r(t)=(t^5+C_1)\,\mathbf i+(t^6+C_2)\,\mathbf j+\left(\dfrac12t^2+C_3\right)\,\mathbf k$

Given $\mathbf r(1)=\mathbf i+\mathbf j$ , we have

$\begin{cases}1^5+C_1=1\\\\1^6+C_2=1\\\\\dfrac121^2+C_3=0\end{cases}\implies C_1=0,C_2=0,C_3=-\dfrac12$

so that the particular solution is

$\mathbf r(t)=t^5\,\mathbf i+t^6\,\mathbf j+\dfrac12(t^2-1)\,\mathbf k$

A. CPCTC b. SAS c. ASA d. SSS

Lyrx [107]

a. CPCTC is your answer

CPCTC means that "Congruent Parts of a Congruent Triangle(s) are Congruent"

If ΔBRM ≅ ΔKYZ (given), then every part inside the triangle is ≅ with the corresponding side.
So, for example Line BR will be ≅ with Line KY, etc

hope this helps

In mrs.smiths class every time you turn in 10 assignments you earn 1 homework pass.Write 3 equivalent ratios if turned in assign

frutty [35]

Answer:

Step-by-step explanation:

For every 10 assignments you get 1 homework pass. So you would multiply them by two and up more.

So here's some of your answers:

10:1

20:2

30:3

40:4

50:5

60:6

70:7

80:8

90:9

100:10

You would just continue this pattern.

WORTH BRAINLIST!!! What is the value of the expression 2 + 3^2 ⋅ (3 − 1)? 20 22 23 32

Wittaler [7]

Answer:

You have to use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), and solve in that order. Your question is:

2 + 32 ⋅ (3 − 1)

First, solve the Parentheses part of the question. 3-1 is 2. Your question is now:

2+32*2

Now, solve the multiplication part of the question. 32*2 is 64. Your question is now:

2+64

This is now an easy problem to solve.

The answer is 66.

Hope this helps! :)
